Question from Carol:

If I have a one acre plot of land, what is the measurement in feet on each of the four sides?

Hi Carol,

An acre is 43560 square feet. An acre plot of land can be of any shape as long as its area is 43560 square feet. The shape might be a square, a rectangle, a triangle, have 5, or 6 or any number of sides. In fact some of the sides might not even be straight lines.

Your plot has 4 sides and if the shape is a square, that is all the sides are the same length and all the angles are right angles, then the length of each side is $\sqrt{43560} = 208.7$ feet long. If the plot is not a square then you need to know much more about the shape before you can determine the side lengths.
